I completely agree with that. If there would be anything like fear then all of us should be afraid of a particular thing. But we see that our subject of fear is different from one another. So I will say that it's a mindset of human being.

I agree with everybody as well.
When you learn to let go. Realize that there is nothing to lose. That there is no point to your life except to live it to the best of your ability. That the opinions of others do not matter. That others cannot dictate your life, you alone allow them to. That whatever happens, will happen. That there is always a way to get out of a situation.
Fear dissolves.
